solid reliable amps that are not overly well known but they do perform, place I work doesnt get many defectives back of those and we have some customers taht absolutely love cadence
I am about to put in a q4000 myself fazes, only problem I have with that amp is I get almost no crossover options on it but it is their lower end 4 channel I knew that when I bought it, but I am sure I will be happy with it
